ToaZZ whom it may concern.-

Be itknown that l, WiLxiE: TI'NRER, .a citizen of :the United States, and a resident ct Anton-nose, in the -,y of 'lulchlenry, State of North Dakota, lave invented certain new and useful improvements in Tank Heaters, of. which the following is a specific ati on My invention is an improvementin tankheaters, and has for its object to provide a demos of the character specified for use in preventing the freezing of water .in tanks,

' water, :as shown, and resting upon the bottom of the water tank.

The improved heater comprises a tea-sing 3 of substantially cylindrical form, having three extensions l, 5 and 6, respectively the said extensions being approximately rectangular in cross section. The main body 3 is separated from the extension & by a partition at fastened securely to the casing 3 at its opposite side edges by means of rivets as shown, its bottom, as indicated at 5, being cut away to form an ash door, and a grate 6 is arranged transversely of the casing 3, the shaking handle 7 of the grate extending into the extension t. V

This grate is mounted to oscillate 0n supporting lugs 8, and may be oscillated'by lifting the cover 10, which is provided for normally closing the top of the extension 4, the said door being hinged to upstanding lugs 11 on the wall of the extension and it has a flange 12 fitting within the upper end of the extension.

This door has a damper opening which may be closed by a damper 13, the said damper being pivoted to the door and slidable thereon and having a handle for manipulating the same. The inner edge of this door 10 abuts against the partition 48 and a cover 1% is provided for covering the top of the Specification of LettersPatent.v

4: is a section on the line of present embodiment vof the inventioncasingr3." This cover 1-): is in two parts, as shown, the body portion 1% covering the top of the'casing 3 while the rear portion 145 has extensions 15 and .16. which cover thetops of the extensions 5 and 6. Thus the body portion 14 of the cover may be moved withoutdisturbing the portion 145 The extensions 5 and 6 are vCOnnected at their-bottoms by vacross trunk or casing 17;

and a draft: pipe 18 extends upwardly from asmoke box -19arranged within the casing 3, the part1t1on20 :hZIVlHQ' a-nipple about which the vdraft pipe engages. I

1A transverse partition 20 is provi'dedin the casing :at the-top of the smoke box, the said partitiolrcloslng also the tops of the extensions 5 and 61 Thedrat't pipe 18 extends from an; opening in the {partition 20- atthe smoke box, and the partition '20 has reed open ng in 1ts top, a cover 2l'be ng provided for closing the opening. This cover2l also; the coverfl i have handles 1 for; convenience :in operating I the same. The smoke box 19 is open at its bottom and at its;

rear wall as shown in Fig. t, the opening at the rear wall op ning lnto the extension 5,

' and'the saidopfenrngis, adapted to be closed,

by a gateor damper 22 which is hinged to I the partition 526,, to-swing into position to closeje1therthe-open bottom of the smoke box er the open rear wall, that is, the communication between the smoke box and the extension 5.

. The damper is operated by means of a sliding rod 23 which is mounted to slide in a guide 24: and in the partition 20, and the rod is connected'to the gate or damper by a link 25. When the rod is moved upwardly from theposition of Fig. e the gate or damper will be swunginto position to close communication between the smoke box and the extension 5, while when the rod is swung downwardly the gate or damper will be swung to close the open bottom-0t the smoke box. Thus a direct or indirect draft is provided.

When the gate or damper 22 is swung upwardly the heated air may pass directly from the combustion chamber into the smoke box and through the flue to the atmosphere. When the damper is swung downwardly to close the lower end of the smoke box the 7 :The dividing walls between the'exten'sions. 6 and and-the'main body 3 are formed by,

through the trunk 17 tothe lowerwend of the extension 5, and thence upwardly in the extension 5 into the smoke box.

partitions 2'6 and 27, which are mounted to slide in guides 28 on the walls of the'casing 3. .Thus either of the said partition walls 2601' 27 may be withdrawn. The partition wall'27 has an opening at its top for placing the extension 6 in communication with the casing 3, while the partition 26-has an openingat its top for placlngthe extension 1 5 in communication with the smoke box.

Referring toFigsr-l and 3, will be noticed that at its bottom the casln'g 3 and the extension' have outwardly extending flugsBO provided with openings by means (of which the heater may be secured tothe bottomof the tank. The fuel-is :fed through the door 21',- the cover lqbeing firstlifted,

and the ashes may be removed through'the compartment 4: by lifting the cover 10. The

amount of air needed may be supplied. by
